[Hackrf-dev] HackRF with Raspberry Pi 2 Overruns

[Derek Murphy]

Donald, I changed the sample to 2e6 and then up to 4e6, both way the
Overrun indicator starts to appear faster and then fills the terminal
window faster.

I am not sure if I have something wrong with the driver or kernel config.
It's a stock kernel from the raspbian distro. I tried a couple of different
USB ports on the pi with no change.
